c-Class BladeSystem N_Port Virtualization

If there are multiple

uplinks, then the

server logins are

distributed equally

among them.

Figure 51 Cisco MDS 9124e Fabric Switch for HP c-Class BladeSystem in NPV mode

.

NOTE:

The NP_Ports in

Figure 51

are on the NPV devices, not the hosts.

Failover policy

The failover policy enables automatic remapping of hosts if NP_Ports go offline. It evenly distributes
the hosts among the available NP_Ports. This policy ensures a smooth transition with minimal traffic
disruption when a link fails between an NP_Port on the NPV devices and an F_Port on the external
fabric. To avoid disruption when an NP_Port goes online, the logins are not redistributed.

NPV mode considerations

Consider the following:

•

Nondisruptive upgrades are supported.

•

Grouping devices into different VSANs is supported.

•

A load-balancing algorithm automatically assigns end devices in a VSAN to one of the NPV core
switch links (in the same VSAN) at initial login.

•

You can connect B-, C-, and M-series fabrics without interoperability constraints (see the release
notes for support information).

•

A flexible licensing option is available (12 or 24 ports, with a 12-port upgrade option on the 12-
port model).

•

You can select to use either switch mode or NPV mode.
